含硼铁精矿工艺矿物学研究

采用传统工艺矿物学研究方法,结合X射线衍射、化学分析、MLA等分析手段对含硼铁精矿的化学组成、矿物组成、矿物嵌布特征进行了详细研究.结果表明:含硼铁精矿中的硼、铁分别主要赋存于硼镁石及磁铁矿中;主要脉石矿物为蛇纹石、云母及碳酸盐矿物;矿石中矿物连晶复杂、共生关系密切,磁铁矿、硼镁石、硼镁铁矿紧密共生,与蛇纹石、云母等密切连生,多呈犬牙交错状或不规则状接触;此研究结果对含硼铁精矿的合理综合利用具有一定的指导意义.

Mineralogical Study of Boron-Bearing Iron Concentrate Ore

The chemical composition， mineral composition， dissemination characteristics of the minerals were detailedly investigated by traditional process mineralogy method and XRD， MLA automatic detection，chemical analysis， etc. The results showed that boron and iron respectively occur in the main form of szaibelyite and magnetite， and the primary gangue minerals are serpentine， mica and carbonate minerals. Crystal stock of minerals is complex and intergrowth ralation of minerals is close， the magnetite， szaibelyite and ludwigite are closely symbiotic， they are usually associated with serpentine， and mica closely in the shape of sawtooth or irregular. The results may provide the basis for the rational comprehensive utilization of the boron-bearing iron concentrate.
